To all whom 'itmay concern:

Be it known that I, HERMAN PAnsoNs, a citizen of the United States, residing at Deer Lodge, in the county of Powell and@` State of Montana, have invented new and. useful Improvements' in Automobile-Tires, of which the following is a specification.

This invention relates to automobile tires.

The object of the invention is inv a ready and practical'manner toprevent escape of air from the entire tire; in case of puncture, to retain the air in segregated cells, whereby should one cell become punctured the remaining ones will be intact and thus serve elfectually to cushion the tire; to provide novel means for securing the rapid lling of all of the cells of .the tire; to preclude the possibility of creeping of the tire upon the rim; to shield the lling channel or duct against liability of damage or injury in use;

'generally to improve and increase the emciency of such tires. Y Gencrallystated, he invention resides in a tire comprising a tube divided by curved or other appropriately shaped partitions into a plurality of cells',"each of which contains a valve that will permit ingress of air to the cell, but which will preclude the escape of air therefrom. The air inlets to the respective cells communicate with a continuous air channel that is formed in that portion of the tire that contacts with the rim, said portion being thickened or reinforced for the double purpose of shielding such air channel and of preventing the tire from creeping upon the rim, or riding thereon .with attending danger of becoming cut and thus rendered useless.

The invention consists further in certain novel details of construction of automobile` tire as will be hereinafter described and claimed. l

In the accompanying drawings forming a part of the specification and in which like characters of reference indicate corresponding arts, Figure 1 is a view in vertical longitudinal section through a portion of a tire and a rim, the tire being constructed in accordance with the present invention. Fig. 2 is a view in transverse section.

Referring to the drawin s, l designates the rim and 2 the spokes o an Ordinar or any preferred form of wheel, and as t lese parts may be ofilany preferred construction, detailed description thereof is deemed unnecessary. t"

(EQ l The invention resides 1n the novel form of tire .which may be constructed in any preferred manner to insure elasticity and durability. The tire 3 is divided by a plurality of partitions 4, which are herein shown as dished, into as many air cells or chambers 5 as may be desired, the cont-our of the partitions operating to reinforce the tire asl a' whole, and also materially to increase 'its elasticity, while at the same time, provlding the air chambers referred to. The rim por' tion 6 of the tire is, yas shown in Fig. 2, reinforced and thickened, for the purpose of increasing the stability of the tire, and to prevent creeping and riding of the tire upon the rim. This rim portion 6 is provided with an air supply channel 7, which, as

clearly shown in Fig. 2 Ais so housed as vt0 be protected against liability of damage in use, whereby the utility of the tire is materially increased. The outer wall of the air channel is-'provided with as many orifices 8 as there are air cells, andicach of the oriices communicates with a cell or chamber as shown in Fig. 2. In order to retain the air within the cells, each is provided with a iap valve 9 of any preferred construction that is adapted tightly to -fit over the orifices 8 and thus seal it in such manner as to hold the air within the chamber under the pressure to which the tire will be subjected in use.

The rim is provided with an ordinary valved inlet tube 10 that communicates with the air channels 7 ','a valve 11 arranged within the channel operating toseal the o ening 12 between the inlet tube 10 and t e air channel.

From the construction herein described, it will be seen that a tire possessing all of lthe necessary requisites to render v.it thoroughly eiiicient in use is provided and further that flattening by leakage of air is positively precluded, as, 1ffone or more cells or chambers 5 are punctured, only this portion of the tire will become flattened, lwhile the remaining portion will still retain its required elasticity. Furthermore, in the event of puncture of one o r more air chambers, those on each side of it will operate in a large measure to prevent undue iiattening.
